  1433. US$10,000 to the Mesa project to support its continuing development.
  1434. Mesa is a free implementation of the OpenGL 3D graphics library and id's
  1435. newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
  1436.  
  1437. The donation will go to Keith Whitwell, who has been optimizing Mesa to
  1438. improve performance on 3d hardware.  Thanks to Keith's work, many
  1439. applications using Mesa 3.1 will see a dramatic performance increase
  1440. over Mesa 3.0.  The donation will allow Keith to continue working on
  1441. Mesa full time for some time to come.
